Sincerely, I'm divided in this one. It does have some great graphics, they come from Illusion game, and they always have some great graphics, and this game even includes animations, in some video format, so you can't control anything, but it sure is a positive point.
Said that, the story is simply bad. The Main Character is a jerk, horny all the time, without any restriction, and some things he does can easily be considered rape, and even a little ugly, but despite that, all girls want to enter his pants. It's not like there is any big plot, or temptation, or anything like that, a girl can hate the MC and minute later is sucking his dick. Married girls are still unable to resist his... whatever. If at least there was some kind of supernatural power, but there isn't. So it's not really believable at all.
Gameplay-wise, it's direct but requires some level of grinding. just a little though. Just choose the girl you want to suck your dick at the day and everything happens naturally.
So, usually in H-games, the story takes a second place, when the story takes up so much of the time in this game, just having a plot "everything goes" kind is detrimental. I'll give it 3/5 but only because the graphics are enjoyable.
